RING SPINNING AND ANALOGOUS MACHINE Filed t. 20, 1931 5 Sheets-Sheet 3nd J David T Viizrlwusa,

ATTORNEY 1y movable ring rail carrying rings 3 upon as 14 depending fromeach of which is the usual traveller 4. The spindles (not shown) aredriven by whorls 5 and carry spools such as 6.

The ring .rail 2 is supported upon lifter spindles 7 at the upper end ofeach of which is a cross-head 8, the lifter spindles 7 passing throughapertures in the spindle rail 1 and each having at its foot a dog suchas 9 connected by means of a chain 10 to the chain rod 11, each chain 10passing by way of jockey pulleys to and over a pulley 12 mounted on apulley plate 13 which is attachedto the spindle rail 1 by brackets suchsaid spindle rail and bolted thereto at 15.

Referring now to Figures 2 and 3, the spindle rail 1 is carried by thelifter spindles,

16 at the foot of each of which is a dog such as '17 to which isattached one end of a chain 18 whereof the other end is secured to acollar 18w fast on a stud 22 mounted suitably on a, fixed part of theframe.

From the point of its attachment to said collar 180, each chain 18 firstpasses over a scrollor spirally grooved roller 19 secured upon acontinuousrotary shaft 20 and then each of said chains 18 passes over aguide pulley 21; also mounted upon the aforesaid stud 22 and thencetothe dog 17.

23 is the rod end iron, the contact face 23a of which is so shaped as topermit the chain rod 11 to have a certain amount of vertical movementinv addition to its normal longitudinal movement, said chain rod 11being forked at its end to accommodate a roller 24 which contacts withthe face 23a of said rod end iron 23.

v The aforesaid continuous shaft 20 receives rotation through the mediumof the buildergotion gearing 25, 26, 27 and the gear wheel 25 is thedriving wheel mounted on the sleeve 25a on the screw shaft 25?).

The gear wheels 26 and 27 are mounted on stud 28 (see Fig. 5) which iscarried suitably by the frame end, and the gear wheel 29 is carriedbythe continuous shaft 20.

During the first half of the building operation the scrolls 19 rotatingwithin the bights or loops of the respective chains 18 are so designedas to maintain the effective length of each chain 18 constant, but,during the remainder of the building operation gradually to lengtheneach chain 18 thus lowering the spindle rail 1 and preventing theballoon of the yarn from becoming too short.

It will therefore be apparent that, by

means ofthe above described apparatus, if the ring rail 2 is, say 4inches higher than the spindle rail 1 at the commencement of thebuilding operation, and

if 10 inch spools are bemg built, when the buildis coinpleted the ringrail 2 will be 14 inches higher than the spindle rail 1. When thebuilding operation commences, the spindle rail 1 is in the normalposition where it remains until the ring rail 2 is, say, 9 incheshigher, that is to say half way, at which point the scrolls 19 commenceto cause the spindle rail 1 to lower at exactly the same rate of speedas the ring rail 2 is traversing and without interruption of therelative movement of the ring rail 2. 5

In this manner the difiiculties incidental to the building of the largerpackages referred to above are overcome and the best conditions forspinning, twisting or the like are maintained throughout the build.-

What we claim is: i 1. In ring spinning and analogous machines includinga spindle rail, spindles carried by said spindle rail, a ring rail,rings carried by said ring rail, a builder motion having a rod end iron,and a chain rod actuated by said builder motion through said rod endiron, said spindle rail and said ring rail both being movable.vertically; means controlling the movement of said ring rail suspendedfrom said movable spindle rail, and means controlling said spindle railso as at a certain point in the operation of said builder motion, tolower said spindle rail together with the ring rail and chain rod at thesame rate of speed as said builder motion traverses said ring rail.

2. In ring spinning and analogous '1nachines including a spindle rail,spindles carried by said spindle rail, a ring rail, rings carried bysaid ring rail, a builder motion having a rod end iron, and a chain rodactuated by said builder motion through said rod end iron, said spindlerail and said ring rail both being movable vertically; lifter spindlessupporting said ring rail, said lifter spindles being supported bychains from said movable spindle rail, and means controlling saidspindle rail so as, at a certain point in the operation'of said buildermotion, to lower said spindle rail togetherzwith the ring rail and chainrod at the same rate of speed as said builder motion traverses said ringrail. v

3. In ring spinning and analogous machines including a spindle rail,spindles carried by said spindle rail, a ring rail, rings carried bysaid ring rail, a builder motion having a rod end iron, anda chain rodactuated by said builder motion through said rod end iron; said spindlerail and said ring rail both being movable vertically; lifter spindlessupporting said ring rail, said lifter spindles passing through saidspindle rail and being connected by chains to said chain rod, each ofsaid chains being engaged by a pulley adjacent said chain rod, saidpulley being supported by said spindle rail, and means controlling saidspindle rail so as at a certain point in the operation of said buildermotion, to lower said spindle rail together with the ring rail and chainrod at the same rate of speed as said builder motion traverses said ringrail.

4. In ring spinning and analogous ma-V chines including a spindle rail,spindles carried by said spindle rail, a ring rail, rings carried bysaid ring rail, a builder motion having a rod end iron, and a chain rodactuated by said builder motion through said rod end iron; said spindlerail and said ring rail both being movable vertically; lifter spindlessupporting said ring rail, said lifter spindles being suspended bychains from said movable spindle rail, lifter spindles supporting saidspindle rail, said spindle rail lifter spindles being suspended bychains passing over s irally grooved pulleys, and means control ed bysaid building motion to rotate said pulleys so as, at a certain point inthe operation of said builder motion, to lower said spindle railtogether with said ring rail and chain rod at the same rate of speed assaid builder motion traverses said ring rail.

5. In ring spinning and analogous machines including a spindle rail,spindles carried by said spindle rail, a ring rail, rings carried bysaid ring rail, a builder motion having a rod end iron, and a chain rodactuated by said builder motion through said rod end iron; said spindlerail and said ring rail both being movable vertically; in combination,means suspended from said spindle rail for controlling the movement ofsaid ring rail, a rod end iron constructed so as to engage said chainrod when the latter has vertical movement as Well as the normal buildingmovement, and means controlling said spindle rail to cause it to remainstationary during a portion of the operation of said builder motion andto cause said spindle rail to be lowered during the remainder of saidoperation.

In testimony whereof they aflix their signatures.
